Local control of propulsion machinery
What is being checked
The inspector is checking whether engineers can transfer propulsion and essential auxiliaries from remote to local control, communicate with the bridge and operate safely after control-system failure.

Answer aloud, then open the preparation point.
1How do you take local control after bridge-control failure?
Notify the bridge, stabilise the plant, select local control in the approved sequence, confirm authority and obey repeated orders through tested communications.
2Which protections remain active in local control?
Identify the actual trips, slowdowns, interlocks and any protections bypassed or changed on this installation.
3How is engine speed or pitch ordered from the bridge?
Use the designated communication and repeat-back method, with engine movements recorded at the controlling station.
4What auxiliaries may also need manual control?
Identify fitted fuel, lubricating-oil, cooling, starting-air, pitch and control-air equipment affected by the failure.
5How is the test performed without endangering the vessel?
Use the planned company test under safe conditions, coordinate all stations and avoid an uncommanded propulsion response.
Where an observation may arise
Engineers cannot explain the actual selector or authority-transfer sequence.
The designated bridge-to-local communication is defective or untested.
Controls, indicators or lighting at the local station are not functional.
Records show only visual inspection, not the required operational verification.
Only the Chief Engineer can operate the emergency arrangement.
Master's practical note
Conduct a tabletop failure from the bridge order to the local fuel or pitch command. Generic knowledge of local control is insufficient if engineers cannot identify this ship's selectors and surviving protections.
Equipment boundary and references
Equipment boundary: Operational testing must be risk assessed and may be simulated where actual transfer could jeopardise navigation. Follow maker limitations and the approved control-system arrangement.
